1. If a vortex flowmeter is applied for mandatory inspection but not sent for inspection according to regulations, and instead tested at a non designated institution, it will have various adverse effects.
.
1. Legal Risks of Violating Metrology Regulations 1 Mandatory calibration of measuring instruments should be carried out by legal metrological calibration institutions or authorized institutions. Sending instruments for self calibration to non designated institutions is a violation and may face warnings and fines from regulatory authorities. It may also affect the recognition of enterprise metrological qualifications. When it comes to mandatory calibration scenarios such as trade settlement and security protection, flow meter data that has not been calibrated according to regulations has no legal effect, which may lead to transaction disputes, inability to protect rights, or security risks caused by inaccurate data.
2. Loss of dust effectiveness in measurement data 1 Testing reports issued by non designated institutions are not recognized by regulatory authorities, and flow meter measurement data cannot be used as legal measurement vouchers. There may be loopholes in the internal measurement management system of the enterprise. When used for production process monitoring or energy measurement, flow meter data that has not been legally verified may have no guarantee of accuracy, which may lead to production parameter loss of control, energy statistics distortion, and affect enterprise operation decisions.
III. Difficulties in Subsequent Verification and Management 1 Due to failure to complete mandatory calibration as required, subsequent reapplication for statutory calibration may requir
2. What measuring instruments are used for calibrating vortex flowmeters?
A vortex flowmeter is an instrument used to measure fluid flow rate, which calculates the flow rate by measuring the angular velocity of the turbine rotation when the fluid passes through the vortex flowmeter.. To ensure the accuracy of the measurement of the vortex flowmeter, some special calibration instruments need to be used for calibration, among which the main calibrators include the following: 1. Standard volumetric measuring instrument: The flow calibration of the vortex flowmeter usually uses a standard volumetric measuring instrument. A certain volume of liquid is completely passed through the vortex flowmeter and the standard volumetric measuring instrument, and then the readings of the vortex flowmeter and the standard volumetric measuring instrument are compared to calculate the error of the vortex flowmeter and determine the calibration coefficient. 2. Static gravity weighing system: If the vortex flowmeter is wide, the flowmeter can also be calibrated with caution using a static gravity weighing system to weigh the weight of the fluid produced by the vortex flowmeter and calculate its flow rate.
3 Liquid level gauge: The liquid level calibration of vortex flowmeter usually uses a liquid level gauge to compare the liquid level of the fluid passing through the vortex flowmete
